Haha I would need more than 30 secs just to press all the buttons needed to solve for x, let alone figuring out the answer and what the question actually is - from what it says, I would interpret it as

[tex]y=\frac{264^{15}.2xyzn}{99}+1-(\pi+\phi)[/tex]

But it could obviously mean many other forms. And like hallsofivy has said, the person is obviously clueless about this kind of stuff and was leaning much towards the humour of this picture rather than the accuracy of its question.

To answer the basic question, "How to solve for x when it's in the exponent?":

You would need to isolate the x-term on one side of the equation, take the logarithm of both sides of the equation (any base, as long as they're the same), move x from exponent of a logarithm to coefficient of a logarithm [itex](\log{3^X} = X \log 3)[/tex]
